Filed: 2022-01-14
Abstract: To provide a stator punched plate, stator core and motor, capable of achieving high cooling efficiency.SOLUTION: An outer circle of the stator punched plate is provided with a structure comprising continuous recess grooves and projections. The recess groove-and-projection structure is used for a cooling medium to flow.
